We need to write a 1500+ Chinese article, 6-8 paragraphs, each 150-250 characters (words? Chinese characters). Must be about "postgres 恢复数据库". Title is given but we should not output title, just normal text. Must be at least 1500 characters, cannot be less than 1050. Need 6-8 paragraphs, each 150-250 characters. So total characters between 900-2000. Must be at least 1500, so need around 1500-1600 characters. 6-8 paragraphs each 150-250 characters => if 6 paragraphs of 250 each = 1500, fits. If 8 paragraphs of 187 each = 1500. Let's aim for 7 paragraphs of about 215 characters each => total ~1505 characters. Must be natural, avoid AI phrases, use short sentences, no fluff. Must not use prohibited words. Must not include title or any extra. Must be 6-8 paragraphs, each 150-250 characters. Let's count characters approximate.
We need to produce Chinese text. Let's craft 7 paragraphs, each about 215 characters. Let's write them.
Paragraph 1: intro about postgres 恢复数据库.
Paragraph 2: discuss backup strategies.
Paragraph 3: discuss point-in-time recovery.
Paragraph 4: discuss PITR steps.
Paragraph 5: discuss pgdump and pgrestore.
Paragraph 6: discuss common pitfalls.
Paragraph 7: conclusion.
We must ensure each paragraph length between 150-250 characters. Let's count approximate characters. We'll write each paragraph and count roughly.
I'll draft paragraph 1:
"数据库宕机后，最怕的就是数据丢失。 PostgreSQL 提供了多种恢复手段，其中「postgres 恢复数据库」是运维人员最常碰到的操作。本文从实战角度，分享几种常用恢复方式，帮助你快速把库拉回去。" Let's count characters: include punctuation? Chinese characters count each. Let's count roughly:
"数据库宕机后，最怕的就是数据丢失。" (12?) Let's count more precisely.
I'll write with maybe 100 characters each paragraph, but need 150-250. Let's aim for ~180 per paragraph.
I'll write paragraphs and then count.
"数据库宕机后，最怕的就是数据丢失。 PostgreSQL 提供了多种恢复手段，其中「postgres 恢复数据库」是运维人员最常碰到的操作。本文从实战角度，分享几种常用恢复方式，帮助你快速把库拉回去。" Let's count characters (including punctuation). I'll count manually:
数(1) 据(2) 库(3) 宕(4) 机(5) 后(6) ，(punct) (skip?) but count as char? We'll count characters including punctuation maybe not needed. Let's approximate: Chinese characters count maybe 45? Let's just assume it's around 70? Might be less. Let's maybe write longer paragraphs to ensure 150-250 characters.
Better to write each paragraph about 200 characters. Let's craft each paragraph with about 200 characters.
I'll write paragraphs and then count approximate.
Paragraph1 (approx 200 chars):
"数据库宕机后，最怕的就是数据丢失。 PostgreSQL 提供了多种恢复手段，其中「postgres 恢复数据库」是运维人员最常碰到的操作。本文从实战角度，分享几种常用恢复方式，帮助你快速把库拉回去。"
Let's count characters (excluding spaces). I'll count each Chinese character and punctuation maybe counts as one. Let's count:
数(1) 据(2) 库(3) 宕(4) 机(5) 后(6) ，(7) 最(8) 怕(9) 的(10) 就(11) 是(12) 数(13) 据(14) 丢(15) 失(16) 。(17) Space? maybe ignore. (18) Post(?) Actually "PostgreSQL" includes letters; count each letter? Might be considered characters but okay. Let's approximate length maybe around 80-90. Not enough. Need 150-250. So need longer.
Let's expand paragraph with more detail.
"数据库宕机后，最怕的就是数据丢失。 PostgreSQL 为了防止这种情况，提供了多种恢复手段，其中「postgres 恢复数据库」是运维人员最常碰到的操作。如果你刚接触这个概念，下面的几段内容会一步步带你了解从备份到恢复的完整流程。"
Now count roughly. Let's count Chinese characters ignoring spaces and punctuation but count punctuation.
数(1) 据(2) 库(3) 宕(4) 机(5) 后(6) ，(7) 最(8) 怕(9) 的(10) 就(11) 是(12) 数(13) 据(14) 丢(15) 失(16) 。(17) Space(ignore) PostgreSQL (letters) maybe ignore but count as chars? We'll just approximate length maybe around 120. Still need more.
Add more: "在实际工作中，面对意外宕机或误删表，往往需要快速定位并执行相应的恢复步骤，否则可能导致业务中断。本文将围绕「postgres 恢复数据库」的几种主流方法展开，帮助你在危急时刻能够从容应对。"
Now maybe total around 180-200 characters. Let's trust it's within 150-250.
We need 6-8 paragraphs each 150-250 characters. Let's produce 7 paragraphs each about 200 characters.
I'll write them and then approximate length.
Paragraph1 (intro) ~200 chars.
Paragraph2 (backup strategies) ~200 chars.
Paragraph3 (point-in-time recovery) ~200 chars.
Paragraph4 (step-by-step PITR) ~200 chars.
Paragraph5 (pgdump/pgrestore) ~200 chars.
Paragraph6 (common pitfalls) ~200 chars.
Paragraph7 (conclusion) ~200 chars.
Total ~1400-1500 characters. Need at least 1500, maybe 1500 exactly. Let's aim for each 215 characters, total 1505.
I'll write paragraphs with roughly 215 characters. Hard to count precisely manually, but approximate.
Let's draft paragraphs.
"数据库宕机后，最怕的就是数据丢失。 PostgreSQL 为了防止这种情况，提供了多种恢复手段，其中「postgres 恢复数据库」是运维人员最常碰到的操作。如果你刚接触这个概念，下面的几段内容会一步步带你了解从备份到恢复的完整流程。" Let's approximate length: maybe 130-150? Might be a bit short. Let's add more sentences.
Add: "无论是全库备份、增量备份，还是基于日志的增量恢复，都离不开合理的备份策略。下面我们先聊聊备份的几种常见方式以及它们的适用场景。" That should increase length.
Now Paragraph1 final:
"数据库宕机后，最怕的就是数据丢失。 PostgreSQL 为了防止这种情况，提供了多种恢复手段，其中「postgres 恢复数据库」是运维人员最常碰到的操作。无论是全库备份、增量备份，还是基于日志的增量恢复，都离不开合理的备份策略。下面我们先聊聊备份的几种常见方式以及它们的适用场景。"
Now count roughly: maybe 200 characters.
Paragraph2: talk about backup types: full, incremental, continuous archiving.
"在日常运维中，最基础的备份是全库快照，它能一次性捕获整个数据库的状态。为了降低备份窗口，很多团队会采用增量备份或流式日志（WAL）归档。PostgreSQL 的归档模式让你可以把每一次写操作记录下来，后期利用这些日志实现点时间恢复。" Let's approximate length ~180-200.
Paragraph3: discuss point-in-time recovery (PITR).
"点时间恢复（PITR）是利用归档日志把数据库恢复到某个具体的时间点。它的核心思路是先把最近的全库备份恢复，然后依次应用之后的 WAL 文件，直到达到目标时间点。这样可以精确还原到故障前的最新数据，避免一次性回滚导致的数据丢失。" Approx 200.
Paragraph4: step-by-step PITR instructions.
"实际执行 PITR 时，要确保数据库启动时打开了 archiving。把 backup 目录里的最新基线恢复后，使用 psql 连上实例，执行 pgrewind 或 pgbasebackup 之类的命令。接着，通过 pgctl promote 将归档日志依次回放，直至达到目标 LSN。整个过程不需要人工干预，只要准备好合适的日志文件即可。" Approx 200.
Paragraph5: talk about pgdump/pgrestore.
"如果只需要恢复单个表或几条记录，直接使用 pgdump 与 pgrestore 会更加灵活。通过 pgdump -Fc 导出自定义格式的脚本，恢复时只需要执行 pg_restore -d 数据库名 dumpfile.dump 即可。
